Every few days, web display (graphics and text) of most current weather station data, except for barometric pressure and rainfall, appears to be incorrect for part of the day. If the historic "Over the Past Day" plots show current values, however, the current values for those variables are correct. Unfortunately, we are unable to address this problem in the near future. We apologize for the inconvenience.

About

The graphs on this page may be unclear on a PC. This appears to be the result of the image shrinking I've done in order to fit two images side-by-side. In Firefox on a Mac, this page will look fine. If you are not using that browser and would like to see a more legible version of the image, try right-clicking on the image and selecting "View Image." On Firefox that gives you the original full-sized image.

Note: The above buttons for accessing the archives will not work unless you are accessing this page in its original form (i.e., at www.npuphysics.org).

Sub-hour archive records prior to 21 August 2009 are provided in 5-minute intervals. Beginning with 21 August 2009, sub-hour archive records are provided at 30-minute intervals. The yearly report for 2009 does not contain data prior to August, due to problems with the data processing server.

Bad data: While the list below is not exhaustive, data during the following periods, and all statistics calculating using that data, are known to be incorrect (local time in yyyy-mm-dd hh:mm format):

  • All data prior to 2007-08-02 13:00: Station testing.
  • 2009-05-27 00:10 to 2009-05-27 08:50: Bad archive files.
  • 2009-06-16 21:25 to 2009-06-17 08:20: Bad archive files.
  • 2009-06-21 04:00 to 2009-06-21 16:50: Bad archive files.
  • 2009-06-21 16:00 to 2009-06-21 16:55: Bad archive files.
  • 2009-07-20 01:50 to 2009-07-20 02:40: Bad archive files.
  • 2009-08-19 19:00 to 2009-08-27 18:36: Problems with the data processing server.
  • 2010-10-27 to 2010-12-06: During this period, the main unit battery was dying, and so there are large periods spread throughout which are filled with bad data.
  • 2011-05: During this month, the repeater transmitter battery was dying, and so there are large periods spread throughout which are filled with bad data.
